The present invention relates to cosmetic, pharmaceutical, and dermatological compositions comprising comb copolymers based on acryloyldimethyltaurine.

Consumer desires and cosmetic product rheology are closely interlinked. Thus, for example, the visual appearance of a cream or lotion is influenced by the viscosity. The sensorial properties, such as consistency or spreadability, determine the individual profile of a cosmetic product. The effectiveness of active substances (e.g., sun protection filters) and the storage stability of the formulation are also closely related to the rheological properties of the products.

In the cosmetics sector a leading part is played by polyelectrolytes as thickeners and gel formers. State of the art are, in particular, thickeners based on poly(meth)acrylic acid and the water-soluble copolymers thereof. The diversity of the possible structures and the diverse possibilities for use associated therewith are manifested not least in a multiplicity of patents filed worldwide since the mid-1970s.

A substantial drawback of the thickeners based on poly(meth)acrylic acid is the heavy pH dependency of the thickening action. Thus, in general, a sufficiently high viscosity is only developed when the pH of the formulation is adjusted to a level of more than 6, i.e., the poly(meth)acrylic acid is in neutralized form. Furthermore, the corresponding compositions are sensitive to UV radiation and also to shearing, and they also impart a sticky feeling on the skin. The handling of such thickeners is also problematic. Since the thickeners are generally in acidic form, formulation involves an additional neutralizing step.

In the 1990s, innovative thickeners based on crosslinked and neutralized polyacryloyldimethyltaurates were introduced into the market (EP-B-0 815 828, EP-B-0 815 844, EP-B-0 815 845 and EP-A-0 850 642). Both in the form of the preneutralized homopolymer and as the corresponding copolymer (®ARISTOFLEX AVC, CLARIANT GmbH), these thickeners are superior in many respects to the poly(meth)acrylate products. For example, acryloyldimethyltaurate-based thickener systems exhibit outstanding properties in pH ranges below 6, i.e., in a pH range in which it is no longer possible to operate with conventional poly(meth)acrylate thickeners. High UV and shear stability, outstanding viscoelastic properties, great ease of processing, and a favorable toxicological profile of the principal monomer make acryloyldimethyltaurate-based thickener systems new, modern representatives with a high potential for the future.

Over the course of recent years a further thickener concept has become established on the market. By hydrophobic modification of conventional poly(meth)acrylates, an access route has been found here to polymers which have both thickening and emulsifying/dispersing properties. Examples of commercial hydrophobically modified poly(meth)acrylates are ®PEMULEN TR-1 and TR-2 from BF Goodrich and ®ACULYN 22, Rohm & Haas. Since these hydrophobically modified polymers are constructed on the basis of (meth)acrylic acid, they also possess the abovementioned disadvantages of the poly(meth)acrylates.

Surprisingly it has now been found that a new class of comb polymers based on acryloyldimethyltaurine (AMPS)—and suitable in the capacity of a thickener, bodying agent, emulsifier, solubilizer, dispersant, lubricant, adhesive, conditioner and/or stabilizer—are outstandingly suitable for the formulation of cosmetic, pharmaceutical, and dermatological compositions.

The use of two or more additives G) is likewise in accordance with the invention.

Crosslinked additives G) may likewise be used.

The additives G) or mixtures thereof must only be wholly or partly soluble in the chosen polymerization medium. During the actual polymerization step the additive G) has a number of functions. On the one hand it prevents the formation of overcrosslinked polymer fractions in the copolymer which forms in the actual polymerization step, and on the other hand the additive G) is statistically attacked by active free radicals in accordance with the very well-known mechanism of graft copolymerization.

As compared with analogous copolymers prepared without the addition of the additives G), those prepared with the addition of additives G) advantageously exhibit a significantly higher viscosity in aqueous solution.

Those used preferably include water; lower alcohols; preferably methanol, ethanol, propanols, iso-, sec- and t-butanol, very preferably t-butanol; hydrocarbons having 1 to 30 carbon atoms, and mixtures of the aforementioned compounds.

The polymerization reaction takes place preferably in the temperature range between 0 and 150° C., more preferably between 10 and 100° C., either at atmospheric pressure or under elevated or reduced pressure. If desired the polymerization may also be performed under an inert gas atmosphere, preferably under nitrogen.

In order to initiate the polymerization it is possible to use high-energy electromagnetic rays, mechanical energy, or the customary chemical polymerization initiators, such as organic peroxides, e.g., benzoyl peroxide, tert-butyl hydroperoxide, methyl ethyl ketone peroxide, cumene hydroperoxide, dilauroyl peroxide or azo initiators, such as azodiisobutyronitrile (AIBN), for example. Likewise suitable are inorganic peroxy compounds, such as (NH₄)₂S₂O₈, K₂S₂O₈ or H₂O₂, for example, where appropriate in combination with reducing agents (e.g., sodium hydrogensulfite, ascorbic acid, iron(II) sulfate, etc.) or redox systems comprising as reducing component an aliphatic or aromatic sulfonic acid (e.g., benzenesulfonic acid, toluenesulfonic acid, etc.).

Serving as the polymerization medium may be any solvents which are very substantially inert in respect of free-radical polymerization reactions and which allow the development of high molecular weights. Use is preferably made of water and lower, tertiary alcohols or hydrocarbons having 3 to 30 carbon atoms. In one particularly preferred embodiment t-butanol is used as the reaction medium. Mixtures of two or more representatives of the potential solvents described are of course likewise in accordance with the invention. This also includes emulsions of mutually immiscible solvents (e.g., water/hydrocarbons). In principle, all kinds of reaction regime leading to the polymer structures of the invention are suitable (solution polymerization, emulsion methods, precipitation methods, high-pressure methods, suspension methods, bulk polymerization, gel polymerization, and so on). Preferred suitability is possessed by precipitation polymerization, particularly preferred suitability by precipitation polymerization in tert-butanol.

The following list shows 67 copolymers with particular suitability for formulating the compositions of the invention. The different copolymers 1 to 67 are obtainable in accordance with the following preparation processes 1, 2, 3, and 4.

Process 1:

These polymers can be prepared by the precipitation method in tert-butanol. The monomers were introduced in t-butanol, the reaction mixture was rendered inert, and then, after initial heating to 60° C., the reaction was initiated by addition of the corresponding t-butanol-soluble initiator (preferably dilauroyl peroxide). After the end of reaction (2 hours) the polymers were isolated by removal of the solvent under suction and by subsequent vacuum drying.

Process 2:

These polymers are preparable by the gel polymerization method in water. The monomers are dissolved in water, the reaction mixture is rendered inert, and then, after initial heating to 65° C., the reaction is initiated by addition of suitable initiators or initiator systems (preferably Na₂S₂O₈). The polymer gels are subsequently comminuted and the polymers are isolated after drying.

Process 3:

These polymers are preparable by the emulsion method in water. The monomers are emulsified in a mixture of water/organ. solvent (preferably cyclohexane) using an emulsifier, the reaction mixture is rendered inert by means of N₂, and then, after initial heating to 80° C., the reaction is initiated by addition of suitable initiators or initiator systems (preferably Na₂S₂O₈). The polymer emulsions are subsequently evaporated down (with cyclohexane acting as an azeotrope former for water) and the polymers are thereby isolated.

Process 4:

These polymers are preparable by the solution method in organic solvents (preferably toluene, also, for example, tertiary alcohols). The monomers are introduced in the solvent, the reaction mixture is rendered inert, and then, after initial heating to 70° C., the reaction is initiated by addition of suitable initiators or initiator systems (preferably dilauroyl peroxide). The polymers are isolated by evaporating off the solvent and by subsequent vacuum drying.

The described grafting of the copolymers with other polymers, which can be carried out optionally, leads to products having a particular polymer morphology and giving rise to optically clear gels in aqueous systems. A potential disadvantage of the copolymers without grafting is a more or less strong opalescence in aqueous solution. The basis for this opalescence is hitherto unavoidable, overcrosslinked polymer fractions which arise in the course of the synthesis and are inadequately swollen in water. This produces light-scattering particles whose size is well above the wavelength of visible light and which are therefore the cause of the opalescence. The described grafting process, which can be carried out optionally, substantially reduces or entirely prevents the formation of overcrosslinked polymer fractions in relation to conventional techniques.

The described incorporation both of cationic charges and of silicon, fluorine or phosphorus atoms into the copolymers, which can be carried out optionally, leads to products which in cosmetic formulations possess particular sensorial and rheological properties. An improvement in the sensorial and rheological properties may be desired in particular in the context of use in rinse-off products (especially hair treatment compositions) or leave-on products (especially O/W emulsions).

The silicon-modified copolymers may partly or fully take over the functions of silicone oils. The use of silicones can be reduced or avoided by means of the copolymers.

In both crosslinked and uncrosslinked form the copolymers exhibit advantageous properties. While crosslinked systems, for example, have exhibited outstanding profiles of properties in respect of emulsion stabilization, it has been possible in particular with the aid of the uncrosslinked versions to thicken surfactant-containing solutions. The same is true of electrolyte-containing systems, which are known to be very difficult if not impossible to thicken with polyelectrolytes.

The copolymers have diverse possibilities for use and are suitable, for example, for use in aqueous-alcoholic and aqueous surfactant formulations, emulsions, suspensions, dispersions, and powders.

The copolymers can be used as thickeners for compositions on an aqueous or aqueous-alcoholic basis, examples being hair gels. The copolymers are additionally suitable as stabilizers, dispersants, and bodying agents for aqueous surfactant preparations, examples being shampoos, shower baths, shower gels, foam baths, and the like.

The thickening action of the copolymers in aqueous surfactant compositions is boosted by an association between the polymer side chains and the surfactants, and can be controlled through the choice of the side chains of the copolymers and through the choice of the surfactants.

The suspending or dispersing and stabilizing action of the copolymers in aqueous surfactant compositions is due to the association of the polymer side chains and/or functional groups in main chain and side chain with the liquid components that are insoluble in aqueous surfactant compositions, examples being silicone oils, and/or the insoluble components, an example being zinc pyrithione.

The copolymers are likewise suitable as thickeners and dispersants, as emulsifiers, suspension media with thickening effect, and bodying agents for emulsions and suspensions, and also as lubricants, tackifiers, thickeners, dispersants and emulsifiers of decorative preparations containing solids. In this context it is also possible to use mixtures of the copolymers. The emulsifying, stabilizing and/or bodying action of the copolymers in emulsions is due to and/or boosted by an association of the polymer side chains with one another, and also by an interaction of the polymer side chains with the hydrophobic oil components.

The emulsions can be alternatively water-in-oil emulsions or oil-in-water emulsions, microemulsions or multiple emulsions. The emulsions can be prepared conventionally, i.e., for example, by hot, hot/cold or PIT emulsification.

The nonaqueous fraction of the emulsions, composed largely of the emulsifier, the thickener, and the oily substance, is normally from 5 to 95% by weight, preferably from 15 to 75% by weight. It follows from this that the emulsions can contain from 5 to 95% by weight, preferably from 25 to 85% by weight, of water, irrespective of whether lotions with a comparatively low viscosity or creams and ointments with high viscosity are to be prepared.

In one preferred embodiment the copolymers are used in rinse-off products, preferably shampoos, body washes, shower gels, and foam baths.

In another embodiment the copolymers are used in leave-on products, preferably skincare compositions, day creams, night creams, beauty creams, nutrient creams, body lotions, ointments, sun protection compositions, lipcare compositions, and deodorants.

They are also suitable, furthermore, for surfactant-free aqueous compositions and emulsions, for example, for hair treatments and hair rinses, and hair gels, and also permanent waving compositions, hair-coloring compositions, and for decorative cosmetics, examples being makeup, eye shadows, lipsticks, mascara, and the like.

In order to adjust the rheological properties of aqueous or solvent-containing emulsions or suspensions the technical literature specifies a multiplicity of different systems. Those known include, for example, cellulose ethers and other cellulose derivatives (e.g., carboxymethylcellulose, hydroxyethylcellulose), gelatin, starch and starch derivatives, sodium alginates, fatty acid polyethylene glycol esters, agar agar, tragacanth or dextrins. Synthetic polymers employed include a variety of materials, such as polyvinyl alcohols, polyacrylamides, polyvinylamides, polysulfonic acids, polyacrylic acid, polyacrylates, polyvinylpyrrolidone, polyvinyl methyl ethers, polyethylene oxides, copolymers of maleic anhydride and vinyl methyl ether, and also various mixtures and copolymers of the aforementioned compounds, including their various salts and esters. These polymers may alternatively be crosslinked or noncrosslinked.

Essential for the invention is that the acryloyldimethyltaurine copolymers described can be employed even without the use of an additional coemulsifier and/or without the use of an additional bodying agent. The use of coemulsifiers and/or bodying agents is therefore not mandatory, but is possible. Combination with other known coemulsifiers and/or bodying agents may be desirable for establishing specific cosmetic profiles and for utilizing synergistic effects.

The compositions of the invention are normally adjusted to a pH in the range from 2 to 12, preferably from 3 to 8.

The nature of the compositions of the invention is extremely advantageous: the emulsions are creamy and ointmentlike and above all do not have the gel-like or even gelatin-like appearance of certain prior art emulsions in which the external aqueous phase is thickened.

The cosmetic feel on the skin is also very good: on application, the emulsion imparts a sensation of freshness and of comfort, and at the same time has a rich and nourishing effect; it is soft and luxurious and in no way sticky.

The examples and applications below are intended to illustrate the invention, though without restricting it thereto (all percentages are by weight). The copolymers used in the examples are representatives of the particularly preferred copolymers 1 to 67 already listed in the description. They were prepared by the indicated processes 1, 2, 3 or 4 using the preferred initiators and solvents.
